Solve the equation for x.
9(2x + 15) = 45
a)
−10
b)
−5
c)
2
d)
10

-5

Step-by-step explanation:

9(2x+15)=4518x+135=4518x=45-13518x=-90x=-90/18x=-5

We move all terms to the left:

9(2x+15)-(45)=0

We multiply parentheses

18x+135-45=0

We add all the numbers together, and all the variables

18x+90=0

We move all terms containing x to the left, all other terms to the right

18x=-90

x=-90/18

x=-5
